Step 1 — Heat the MilkPour the milk into a saucepan and heat to 180°F (82°C). This kills any unwanted bacteria and changes the protein structure so your yogurt sets thick. Stir occasionally to prevent scorching.
Step 2 — Cool It DownLet the milk cool to 100°F (37°C). You can speed this up by placing the saucepan in a cold water bath. Patience matters here — if the milk is too hot, it will kill your probiotics.
Step 3 — Mix in the Good StuffWhisk in the prebiotic fiber (inulin) until fully dissolved. Then crush your probiotic capsules and whisk those in too. The prebiotic fiber feeds the bacteria during fermentation, which is what makes this yogurt so potent.
Step 4 — Ferment for 36 HoursPour into your container and place in your yogurt maker or Instant Pot set to the yogurt function. Maintain a steady temperature of 100°F for 36 hours. Don't stir, don't peek excessively — just let the bacteria do their work.
Step 5 — Chill and EnjoyAfter 36 hours, your yogurt should be thick and tangy. Refrigerate for at least 2 hours before eating. It will thicken further as it cools.
